SHUTTLE-FEELER FOB LOOMS.

Specification of Letters Patent.

Patented May 25, 1920.

Application filed November 15, 1919. Serial No. 338,191.

To all whom it may concern:

Be it known that 1, JOHN TARANTO, a citizen of the United States, and resident of "Waltham, county of Middlesex, State of Massachusetts, have invented an Improvement in Shuttle-Feelers for Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to improvements in shuttle feelers for looms and the object thereof is to provide a novel shuttle feeler which will act on detection upon an improperly boxed shuttle, through the warp stop mechanism to effect a stoppage of the loom. A further object of the invention is to provide a shuttle feeler of the character above described which can be readily applied to a usual commercial type ofloom without modification nisms of the loom.

The present invention is disclosed herein as embodying the well'known Crompton and Knowles type of loom, but is applicable to other commercial typesof looms. I

lhe object of the invention is to provide a supplemental or additional stop mechanism, to the usual protector mechanism for looms,

which will insure the stoppage of the loom when the shuttle is improperly boxed. The

usual protector mechanism comprises an arm- I which rests against the binder of the shuttle box and when the shuttle is properly positioned in the box the arm is actuated in such a manner as to remove the dagger from the path of a hunter which actuates the knockoif mechanism. It is possible that. the shuttle may enter the box sufliciently to operate the protector mechanism, but still not far enough to inclose the shuttle Wholly within the box. lnsuch case it is not properly positioned to be engaged-by the picker stick and receives the action of the picker stick only during the latter portion of the movement of said picker stick so that the shuttle may be forced only part-way across the loom, thus causing a smash when the lay beats up.

In looms of the Crompton and Knowles type, and in other looms, which are provided with transferring mechanism, the shuttle mayv enter the box sufficiently to actuate the protector mechanism so as to prevent knockoff, but still not far enough to be properly of the usual mecha positioned in relation to the transfer mecha-v nism. The present invention contemplates the prov1s1on of an additional stop mechanism which will be operated by engagement with the end of the properly positioned shuttle and insure knock-0d. The present invention may also be employed in automatic filling replenishing looms which embody a shuttle feeler since the shuttle feeler mechanism merely acts to prevent transfer and not to effect the stoppage of the loom.

It will thus be seen that the present stop mechanism constitutes an additional safeguard which will insure the proper operation of the loom and more certainly prevent the possibility of smashes. Furthermore, by

in looms, whether of the automatic filling replenishing type or the ordinary or box type of looms, 1S safeguarded.

In automatic filling replenishing looms the present invention may be employed as a substitute for the usual shuttle feeler mechanisms as will be obvious and, when so used will effect the, stoppage of the loom upon detection of animproperly boxed shuttle, instead of merelypreventing transfer.

@ther objects and features of the invention will more fully appear from the following description and the accompanying drawings and will be pointedout in the annexed claims. y

A preferred embodiment of the invention is disclosed herein as applied to the well known Crompton and Knowles type of loom embodying a warp stop mechanism, certain portions of which are disclosed in the patent to W'yman, No. 665,713, granted January 8th, 1901. y

In the drawings:

Figure 1 is a side elevation of a portion of a loom having a preferred embodiment of my invention applied thereto, themechanisms not directly involved in the operation of the invention being omitted for the purpose of clearness.

Fig. 2 is a detail plan view of the connection between sections of the extensible feeler.

The invention as illustrated in the accompanying drawings as applied to the well the portions of which illustrated in the drawings comprise theusual side frame 1 breast beam 2 and arch bar 3 connecting the sides 7 htlv having a head 31 which is clamped upon;

of the frame the lay 4 which iscarried by the swords 5 and oscillated by the puma, 6 in the ordinary manner. A shuttle box 7 is carried upon the lay 4 and receives the usual shuttle 8- which is reciprocated across the race upon the lay by the usual picker sticks, not shown. 7

1 The loom illustrated is' provided with a shipper lever 9 which is retained in a notch in a shipper plate 10secured to the end of the breast beam and desirably is formed with a resilient lower portion 11 normally tending to actuate the shipper to stop the loom when disengaged from the notch.

Suitable knock off mechanismis provided which as illustrated comprises a hook shaped member 12 having a plate engaging the shipper 9, the hook 12 being carried at the end of a link 13 which is connected at its oppositeend to the upper end of a rocker 14 which is pivotally mounted upon a shaft l5carrieda suitable boss 16 mounted uponfor"integral-with side frame l; The

I rocker l4 normally is" held in'vertical position so that a luglT projecting from'it nor mally engages a flange or ear 18'projecting upwardly from the] boss =16.i A dagger 19 projl ecting laterally from a sleeve .20 pivotally meuiaeeupon a stud 21 upon theupper end of the rocker l4 is adaptedto cooperate with a hunter 22 carried by a bracket 23 see cured to the lay and depending therefrom.

i The ,daggerl9 normally, is held pin or the -path the hunter 22;" preferably being held abovesaid path by supporting arm underlyinga shoulder 25 on said collar; the

' supp'ortinggarm '24 beingcarriedby a shaft journaled inthe' rocker 14-and having at 1 'itsop po'site endian actuating arm 2"? which is connectedibykalink 28 to the warpstop Wm'echanism; the construction being such that. npon'endwise movement of the link 28 in either directiomthe supporting arm 24 will, be rocked from-*beneatl1 V 5 i g r {shoulder 25 oi the collar 20 and will permit the L supporting the; dagger i9 to drop into the path of the hunter upon the rearward movement of the 'lay. When therefore the hunter 22 engages the-dagger l9 it-willoscillate the rocker 14 about its pivot'15 thereby drawing uponthe Q link 13 and causing the latter to release the shipper from the notch inwhich it is nor? mally held during the operation of the loom. =The resilient portion 11 of the shipper thereupon moves the shipper away from the side of the'loom'. The shipper by such movement is arranged to actuate the usual member29 which controls aclutch, or belt shifter and brake for stopping the 100111.

In order thatsubsequent oscillations of the lay "may not: repeatedlyactuate the the member 29, the arm 30 being positioned to engage a downwardly extending arm or tail 32 connected with orformed integral with the collar 20; these parts being so constructed that upon lateral movement of the member 29 the arm 30 will actuate the tail 32 to rock'the sleeve 20 sufliciently to raise the dagger above the path of the hunter whereupon the supporting arm 24 will again engage the shoulder 25 on said sleeve and retain the dagger 1D. inoperative positlon.

The warp stop mechanism as illustrated is substantially identically disclosed in the Wyman Patent No. 665,7l3 aforesaid and comprises a casing 33 which contains the usual drop wires and supports at its top the lease-rods 34, 35 over which the warps are carriedithedrop wires being supported by the warps iii-the usual manner and adapted upon breakage of a warp, or to great slaclc,

ness therein to drop into the path of a Viv 'brator whichis secured to a'shajftg36 jbu'i naled' ina bracket 37-pending from the oas;

ing 33 the shaft36'being"oscillatedithrough an arm 38 securedzthereto, 7

"Movement is imparted .to the arm 38 0f the vibrator through a transmitter consist- :SlQliO which receivesfa stud41 upon the end 'ofarmc3'8}. Thetransmitter lever i's' pivoted' upon stud- 42' extending outwa'rdly from i ;the elbowbf' an actuator in the form of a r hell; crank lever 43- which is" pivotally main frame of; the machine; 7 The other to a link 46 which isreciprOcated Lfrom; a

fmounted'upon a stud 44 projecting from the i ic H ,arm of the bell Cl'lfllk' l6V6Il 1S COIlIlQClZQCl a cam upon cam shaft ofthe loom; The

arm 47 provided with a stud 48which nor- 7 m'ally isrpositionedin axial alinement with V 1 the aXisof the :pivot' 44' of the bell crank Y ing the I sid'e of the transmitter normally tends to hold saidtransmitter in such posi- 7 tion" that the stud 48 to which the link 28 is transmitten 39 has an upwardly projecting connected is in axial alinement with the pivot upon which the actuator is mounted. In theoperation of the warp stop mechanism' the reciprocation of the link 46 causes an oscillation of the actuator 43 about its pivot 44 thereby imparting through the transmitter 39 a vibratory motion to the arm 38 of the vibratonand causing the vibrator' to move beneath (the drop wires which are supported upon the warps. When, h'owevenfa drop wire falls" or is let down by reason of the slackness of the warp into the path of the vibrator, the vibrator will be arrested and the movement of the actuator thereupon will rock thetransmitter about its pivotal stud 42, thereby moving the stud 48 at its end in an are about the pivot 12 so that the link 28. will be thrust endwise in one direction or the other sufficiently to release the supporting arm 24 from its engagement with the shoulder upon the dagger supporting sleeve 20 thereby permitting the dagger 19 to drop into the path of the hunter so that the latter will rock the arm 14: to knock off the shipper as above described. The mechanism thus described may be and is a usual form employed in the commercial looms of the Crompton and Knowles type.

The present invention consists in applying to the warp stop mechanism a shuttle'feeler which is adapted to initiate the action of the knock-0H mechanism through the warp stop mechanism when said shuttle feeler engages an improperly*boxedshuttle. The shuttle feeler mechanism which is illustrated as applied to the loom havingjthe warp stop mechanism above described is of a very simple character and comprises an arm or a rod preferably made in extensible sections 50, 51, one section being connected to the stud 48 upon the end of the transmitter and the other section providedwith the hook-like extensi'on 52 positioned adjacent the mouth of the shuttle box 7. If, therefore, the shuttle does not sufiiciently enter the box, or if it rebounds after entering the box so as to project beyond the end of the box it will engage the portion 52 of the shuttle feeler as the lay moves forward in its beat up and will pull the shuttle feeler lengthwise thereby rocking the transmitter 89 forward, acting through the link 28 to rock the supporting arm 24: from beneath the'shoulder on the.

dagger supporting collar 20 so that the dagger will drop into theipath of the bunter 22, which upon the rearward movement of the lay will operate the knock-01f mechanism. Any suitable means may be provided for supporting the shuttle feeler. As illustrated herein the section 50 of the shuttle feeler is slidably mounted in a suitable guide 53 in a bracket 5% secured to the arch bar 3.

Any effective means may be employed for extensibly adjusting the shuttle feeler. In a preferred embodiment of the invention illustrated in the drawings the sections 50, 51

of the shuttle feeler extend through sleeves 55, 56 which are provided with suitable clamping screws 57 58 which, when set up,

will clamp the sections 50, 51 firmly against each other and to the collars. It will be understood that the embodiment of the invention disclosed herein is illustrative and not restrictive and that the invention may be applied to different forms of warp stop mechanism and that other feeler constructions may be employed within the meaning andscope of the following claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is: Y

1. In a loom comprising a lay and warp stop mechanism, a shuttle feeler connected to said warp stop mechanism and operable upon detection of an improperly boxed shuttle to actuate said warp stop mechanism to effect a stoppage of the loom.

2. In a loom comprising a lay and warp stop mechanism includinga vibrator, an

actuator, and a transmitter, and means operable by the movement of said transmitter for effecting a stoppage of the loom; a shuttle feeler connected to said transmitter operating upon detection ofan improperly boxed shuttle to actuate said transmitter to cause a stoppage of the loom.

8. In a loom comprising a lay and warp stop mechanism including a vibrator, an actuator, and a transmitter, and means operable by the movement of said transmitter for efiecting a stoppage of the loom; a shuttle feelers comprising a rod having a shuttle engaging member positionedv adjacent the mouth of the shuttle box, said rod being connected at its opposite end to said transmitter whereby upon engagement of said shuttle feeler with an improperly boxed shuttle during the forward movement of the lay said transmitter will be actuated to effect the stoppage of the loom.

l. In a loom comprising a lay and warp stop mechanism including a vibrator, an actuator and a transmitter, and means operable by the movement of said transmitter for effecting a stoppage of the loom; a shuttle feeler comprising a shuttle engaging member and an extensible member connected to said transmitter whereby said shuttle engaging member may be properly positioned in relation to the path of the shuttle and said transmitter operated upon detection of an improperly boxed shuttle to cause a stoppage of the loom.

In testimony whereof I have signed my name to this specification.

JOHN TARANTO.
